Which of these happens to astronauts in space without the pull of gravity?
A
Their vertebrae spread out.
B
They cannot eat solid food.
C
They shrink a few inches.
D
Their hair all falls out.
Answer:A
Explanation: I looked it up
Astronaut's vertebrae spread out in space without the pull of gravity.
What do you mean by pull of gravity?Gravity is a force that attracts all objects towards each other – every object with mass pulls on every other object with mass. When a person jumps off a chair, the person is attracted to the Earth and the Earth is attracted to the person.
The average gravitational pull of the Earth is 9.8 meters per second squared (m/s2). The Earth is made of different substances like air, rock, and water. These substances have a different amount of mass in a certain amount of space (density).
The measure of the pull of gravity on an object is called weight. For an object to have weight it must have mass. Weight can be calculated on Earth by multiplying the mass of an object in kilograms by the acceleration of gravity, which is 9.8 m/s2.

Which of the following actions increases the volume of your lungs?
d. Gases move from areas of lower pressure.
c. Air pressure increases inside the lungs.
a. The diaphragm flattens and moves downward.
b. The rib cage becomes smaller.
Answer:
B
Explanation:
During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle's Law

Answer:
Transpiration is loss of water vapor from leaves. Guard cells regulate whether stomata are open or closed based on availability of water in the plant. When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphereExplanation:
The gas exchange of plants is part of the cellular respiration process, where the plants both remove and release gases into the atmosphere. This exchange happens through structures present in the leaves of plants, which are called stomata. Stomata function as doors, if they are closed it is impossible for the plant to promote gas exchange, but if they are open. Transpiration occurs with the release of water vapor through open stomata. It is in this water vapor that the plant releases oxygen into the atmosphere.
The opening and closing of the stoma is a highly regulated process, because opening the stoma makes the plant lose water. In this case, the guard cells are responsible for opening and closing the stoma whenever necessary and the plant has good water levels.

One autumn, a beech seed blows into a sunny meadow. Following a cold, wet winter, it sprouts. The seedling grows into a sapling. The sapling grows into a taller tree. After several years, it grows lateral branches. Each spring, these leaf, making a shady, cool space under the tree. Over the years, leaf litter decays, forming deep, rich soil. Nevertheless, over time the population of meadow grass under the tree declines. What limiting factor has affected the grass's growth?
Answer:
Accumulation of waste products.
Explanation:
The accumulation of the waste products under the tree is the limit factors that affects the growth of the grass. The accumulation of the waste products proposes that the molecules are damaged by the oxidation process and they are accumulated on the soil.
The leaves of the beech tree shades and falls on the ground and it decays there forming a rich soil. It covers the grassland nearby. Also the beech tree branches out making a small canopy over the grassland. So sunlight is prevent to reach the ground. This limits the growth of the meadows and thus the population of the meadow grass is seen to decline under the tree.

Put the following molecules in order of the correct sequence they are made in protein synthesis.
Reorder answers
RNA
Protein
Gene
Answer: 1. messenger RNA (mRNA). 2. rna, gene, protein. brainliest?
Explanation:
The end result of transcription is mRNA, and the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.
Transcription is the process in which a segment of DNA is used as a template to synthesize a complementary mRNA molecule. It occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. During transcription, the DNA molecule unwinds, and an enzyme called RNA polymerase binds to a specific region of the DNA known as the promoter. The RNA polymerase then moves along the DNA strand, synthesizing a complementary mRNA molecule using the base pairing rules (A with U, G with C).
The end result of transcription is the production of mRNA. mRNA is a single-stranded molecule that carries the genetic information from the DNA to the ribosomes in the cytoplasm. It serves as a template for translation, where the information encoded in the mRNA is used to synthesize proteins.
Regarding the sequence of molecules in protein synthesis, the correct order is as follows:
Gene: A gene is a specific sequence of DNA that contains the instructions for making a protein. It serves as the starting point for protein synthesis.Transcription (RNA): Transcription is the process in which an mRNA molecule is synthesized from a DNA template. This step occurs in the nucleus.mRNA: The mRNA molecule carries the genetic information from the gene to the ribosomes. It serves as the template for protein synthesis.Protein: Protein synthesis occurs during translation, where the mRNA is read by ribosomes, and amino acids are assembled in the correct order to form a protein.Therefore, the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.

In dogs, spotty fur is a recessive trait. Show a cross between two dogs that are heterozygous for spotty fur. What is the likelihood of these dogs having puppies with spotty fur?
Answer:
The correct answer is - 25% chances of having puppies with spotty fur.
Explanation:
In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:
Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive
Punnett square:
S s
S SS Ss
s Ss ss
By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.
